Be sure that you have the room to safely put it where, 1) it won't over heat and burn something. 2) secure It so it doesn't shift or change its position somehow. The Reiff system does not come with a timer but Wallmart has them for under $10. A 100 Watt will be marginal at best. I had a 200 Watt placed inside a sheetmetal pipe just underneath the cowl so the heat would rise from the bottom up and left on all the time and it was marginal at best!
